The Internet of Everything (IoE), clearly a 21st century's technology, brilliantly plays with digital data obtained from analog sources, bringing together two different realities, the analog (physical/real), and the digital (cyber/virtual) worlds. Then, with the boundaries of IoE still analog in nature, the required functions at the interface involve sensing, measuring, filtering, converting, processing, and connecting, which imply that the analog layer governs the entire system in terms of accuracy and precision. Furthermore, such interface integrates several analog and mixed‐signal subsystems that comprise mainly signal transmission and reception, frequency generation, energy harvesting, data, and power conversion. This paper sets forth a state‐of‐the‐art design perspective of some of the most critical building blocks used in the analog/digital interface, covering wireless cellular transceivers, millimeter‐wave frequency generators, energy harvesting interfaces, plus, data and power converters, that exhibit high quality performance achieved through low‐power consumption, high energy‐efficiency, and high speed.

鸟瞰21世纪的模拟和混合信号芯片

万物互联（IoE），显然是21世纪的技术，可以很好地处理从模拟来源获得的数字数据，将模拟（物理/现实）和数字（网络/虚拟）世界这两种不同的现实融合在一起。然后，由于IoE的边界本质上仍然是模拟的，因此接口上所需的功能包括感测，测量，滤波，转换，处理和连接，这意味着模拟层在准确性和精度方面控制着整个系统。此外，这种接口还集成了几个模拟和混合信号子系统，主要包括信号发送和接收，频率生成，能量收集，数据和功率转换。
